"Staff members here have been in a state of readiness to treat Ebola patients since we were first visited by the U.S. State Department in early August," the hospital said in a statement. "As with previous patients we've treated here in recent months, per State Department regulations, we would only have confirmation when a plane is en route with a patient aboard. This is not the case right now."

The virus has killed more than 5,000 people, according to the World Health Organization. More than 14,000 patients have contracted Ebola since the first cases were reported in March, making it the largest outbreak ever.

However, Dr. David Nabarro, who is heading up the United Nations efforts to fight Ebola, said last week that there are signs the rate of infections is slowing and that he was "incredibly optimistic that in the coming months we could certainly see a diminution, and hopefully in the next year the outbreak will come to an end."

The U.S. military is scaling back its planned Ebola response deployments from 4,000 troops to 3,000, due to a greater-than-expected number of contractors available in Liberia to provide support such as construction work.
